我有一个构建过程稍微复杂的应用程序，作为 CMake 的新手，我想知道是否有人可以为我提供任何指示。
在预设情况下，该应用程序由一个可执行文件组成，该可执行文件由 src 中提供的源代码树构建并包含文件夹。
它需要一些库才能工作，其中最大的库是 Boost 和 Python。Python 嵌入在应用程序中，Boost 需要在编译时了解自定义 python 安装。我也使用 Qt，但我只是为此链接到系统 Qt。
最后我想要的是一个 stage 文件夹，其中包含已编译的可执行文件，以及一个包含所需 boost 和 python 库的 lib 文件夹。
目前，我有一个 CMakeLists.txt 文件，我正在使用 ExternalProject 从源代码的 bzipped tarball 构建 Boost 和 Python。当我从前缀安装目录中复制出编译的库时，它会变得有点混乱。
事情正在发挥作用，但我有一种感觉，我在做事情非常倒退。我有时会在嵌套的子目录中看到多个 CMakeList，但不知道它们与我的项目有何关系。任何从事过类似范围项目的人都能够权衡并给我一些建议吗？
我应该补充一点，我希望在不久的将来将 Windows 作为一个平台，并且目前正在 Linux 上运行。
注意：这是我当前的 CMakeLists.txt，我意识到 boost 没有配置，并且没有完全移动到 stage 文件夹。我一直在手动执行此操作，但在深入挖掘自己之前我想问一下:)
谢谢！
